SINCLAIR J. JOHNSON,- OF NEYV YORK, N. Y.

DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 571,482, dated November17, 1 896.

Application filed February 24, 1896. Serial No. 580,558. (No model.)

To on whom it may concern.-

Be it known that I, SINCLAIR J. JOHNSON, a citizen of the United States,and a resident of the city of New York, in the county and State of NewYork, have invented certain new and useful Improvements in Dumping Cars,of which the following is such a full, clear, concise, and exactdescription as will enable others skilled in the art to which myinvention appertains to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.

My invention is applicable for use upon hopper-bottom gondola cars,ore-cars, and some other styles of dumping-cars. It has for its objectthe combination with the gate or gates which close the exit for theload, of hangers and mechanism for opening and closing the same, so asto avoid some of the difficulties heretofore experienced and afford amore convenient means for holding the gate or gates open or closed; andthe invention consists of the parts and combination hereinafter morefully described, and pointed out in the claims.

The drawings illustrate my invention as applied to a hopper-bottomgondola car provided with oscillating gates suspended from above, asmore fully described and claimed in an application made by me on evendate herewith, Serial No. 580,556.

Figure 1 of the drawings is a side view or elevation of a portion of ahopper-bottom gondola car, showing one end of two gates which close theexit for the load at the bottom of the hopper, and also shows thehangers by which the two gates are suspended and the lever mechanism foropening and closing them, the gates being shown in this figure asclosed. Fig. 2 is a similar view of the same part, but showing the gatesas open. Fig. 3 is a similar View showing the hopper closed at thebottom by one gate only, the gate being suspended by two straps, each ofwhich is pivoted at each end, so as to swing both from the pointssecured to the car and to the gate. In this figure the gate is shown asbeing operated by a modified form of the mech-' anism shown in Figs. 1and 2. Fig. 4 is a similar view of the same, showing the gate open. Fig.5 is a detail section ofa portion of the car and one of the gates ofFigs. 1 and 2, looking at the hopper, the gate, and lever connections inthe direction of the length of the car. I In the drawings A representsthe side sill of the car, and B the hopper of a hopper-bottom gondolacar. In such a car the load passes out at the bottom of the hopper,which is either closed or opened by the gate, as the case may be. Alldumping-cars are not, however, provided with a hopper, technically socalled, and hence this word is used in a broad sense for the purpose ofdesignating thereby the part of the car which is provided with an exitfor the load, and which exit is opened or closed by a gate or gates.

The gates O and O are shown in the drawings as being suspended from thecar, for which purpose they are secured by bolts or pivots o c tometallic hangers or straps 'b b, pivoted at their upper ends by bolts aa, which pass through the side sill A and through the hopper-iron A orthrough the side sill and a plate a. The hangers shown in Figs. 1 and 2each have one arm I) b extending downward at an angle from thepivot-bolts a a, and which arm is rigidly secured to the inner edge ofthe gate, and the straps b b of Figs. 3 and 4 are pivoted above and atthe gate.

The gates shown are preferably made of a frame of Z-iron cl for theouter and inner edges and of angle-iron d for each end, firmly rivetedor bolted together, and which frame I is floored with suitable plank. Atthe rear of each end of the gate a flat piece of iron (1 of sufficientstrength is riveted on the Z-iron d and extends up above the same, so asto catch against the hopper-iron A when the gates are closed, and thisiron 01 may be made go to work against a guide (not shown) in order toprevent lateral or other motion.

The mechanism for opening and closing the gates consists of a shaft 6,which may have one end square or otherwise adapted to reoeive a wrenchfor turning it, or this shaft may have a crank-arm attached to it forthis purpose. The shaft e is supported by platebrackets c, which aresecured to the side sill A by suitable bolts. e a notched disk or awheel e is secured out side of the supporting-bracket, the notches beingadapted to receive a dog or pawl e pivoted to the bracket and which actsas a lock- On one end of the shaft 10o ing device to prevent any turningof the shaft. The pawl e is shown as being operated by an eccentric 8which is also secured to the bracket 6.

On the shaft eand inside of the plate-brackets e an armed crank orequivalent device is rigidly secured, and, as shown in Figs. 1 and 2,one arm, f, of this crank is pivotally secured to one end of ahorizontally-moving lever-bar f, which has its opposite end pivoted tothe gate-hanger straps b of the gate 0. The other arm, f of the crank isalso pivotally secured to one end of a horizontally-moving lever-bar fand the other end of this bar is likewise secured to the hanger-strapsZ) of the gate 0. In Figs. 3 and 4, where only one gate is shown, theshaft has only one crank-arm f, which is pivotally connected with thebar f, the other end of which is pivotally connected with a lug g, fixedon the gate 0.

The gates being closed, as in Fig. 1, and a wrench being applied to theend of the shaft e, and the shaft being partially rotated, thecrank-armsfandf will by this motion change their position and move thebars f and f in a horizontal direction, which in turn will push thehanger-straps b and b, so as to swing them on the pivots a ct, therebycausing the gates C O to open and assume the position shown in Fig. 2. Areverse movement of the shaft e will have the opposite effect and closethe gates. I11 Figs. 3 and 4 the mechanism shown for opening and closingthe gate operates, essentially, the same way, but as only one gate isshown the shaft is made to operate a single crank-arm and connectionsfor the same with and to the gate.

It is obvious that changes may be made in the detail of construction andin the arrangement of the parts without departing either from the spiritor substance of my invention, and I do not therefore confine myself tothe exact forms shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a du mping-car, the combination of one or more gates adapted toclose the exit for the load, hangers for suspending said gates at eachend and at both edges a shaft secured to the car and provided at each ofits ends with one or more crank-arms and one or more horizontally-movinglever-bars having connection with said crank-arms and with the hangersfor said gate or gates, whereby the same may be opened or closed by apartial rotation of said shaft.

2. In a dumping-car, the combination of one or more gates for closingthe exit for the load, hangers for suspending said gates at each end andboth edges a shaft secured to the car and provided at its ends with oneor more crank-arms, a ratchet and pawl adapted to retain the said shaftin a fixed position and one or more horizontally-moving leverbarsconnected therewith, and with the hangers for said gate or gates foropening and closing the same as said shaft is partially rotated.

3. In a dumping-car, the combination of two gates for closing the exitfor the load, hangers by which said gates are suspended at both ends andat each edge, a shaft secured to the car and provided at its ends withtwo crank-arms, and horizontally-moving leverbars connected therewith,and with the hangers for the gates respectively, substantially asdescribed.
